MIAMI -- Dwyane Wade of the NBA champion Miami Heat had surgery today on his left knee, and is expected to need up to eight weeks to fully recover.

Wade was bothered by knee pain and swelling throughout the playoffs. He had fluid removed midway through Miami's second-round series with Indiana and needed treatment several times a week during Miami's run to the title.

He opted to have the knee surgery early in the offseason in Miami with hopes of being ready for the start of training camp this fall. The surgery forced Wade to withdraw from consideration for the U.S. Olympic team.
